Ability to rename the 'Email confirmation to' field on anonymous portal

Current Behavior

If the Service Desk portal is accessed anonymously, an 'Email confirmation to' field will show up on the portal. Given that this is not included on the request type form by the SD Admins, they will not be able to rename the field as they wish.

Desired Behavior

As a Service Desk admin, I would like to have the ability to rename this field.
